What the publisher says

Attributed to the source that supplied each field. Treated as claims, not facts.

Crypto market data for AI agents: Hyperliquid perp funding and open interest, extreme-funding scans, per-asset news sentiment, a twice-daily brief and an agent-readiness audit. Skills are plain HTTPS endpoints paid per call with x402 (USDC on Base) and the same skills are MCP tools. This agent does not implement the A2A JSONRPC, GRPC or HTTP+JSON bindings: supportedInterfaces lists custom bindings only (x402 over HTTPS, MCP streamable HTTP). Not financial advice.
